The cabinet consists of inverter, low-voltage electrical
system,SIEMENS programmable controller,signal isolation
converter,analog acquisition module,touch
screen,temperature,pressure transmitter. All above are composed of
one set of complete LNG filling station equipment,control and
protection system. It has the pump, valve, tank control, alarm,
shutdown function. Also can be automatic operation, control and
protection for gas station , fault with automatic alarm,automatic
shutdown, fault diagnosis etc..PLC is a modular structure and easy to expand and adjust the
control mode according to the process requirements. The analog
acquisition precision of 12 bits can change the effective detection
of the temperature, the pressure value of the real-time working
condition; touch screen online can achieve a variety of parameter
settings, modify, call and monitoring equipment.Electric control cabinets include PLC control cabinet and frequency
distribution cabinet. PLC control cabinet finish filling all the
equipment one by one. Regarding to the weak part of frequency
distribution ,the cabinet complete frequency control and aerated
pump station distribution function, which belongs to the high
voltage part.
